Predicate logic | Rules of inference
In predicate logic, existential instantiation (also called existential elimination) is a rule of inference which says that, given a formula of the form , one may infer for a new constant symbol c. The rule has the restrictions that the constant c introduced by the rule must be a new term that has not occurred earlier in the proof, and it also must not occur in the conclusion of the proof. It is also necessary that every instance of which is bound to must be uniformly replaced by c. This is implied by the notation , but its explicit statement is often left out of explanations. In one formal notation, the rule may be denoted by where a is a new constant symbol that has not appeared in the proof. (Wikipedia).
The idea of ‘atonement’ sounds very old-fashioned and is deeply rooted in religious tradition. To atone means, in essence, to acknowledge one’s capacity for wrongness and one’s readiness for apology and desire for change. It’s a concept that every society needs at its center. For gifts and
